Definitions

  • the invention relates to an adapter coupling for pushing onto the water-emitting end of a water outlet, in particular a tap, with the production of a watertight connection with an approximately hood-shaped or bell-shaped socket, which has a socket opening, which faces towards the water-emitting end and is surrounded by an annular socket edge, in its Socket interior can receive the water-releasing end and which is provided with a water outlet, with an elastic seal which has a central opening and is arranged in the region of the socket opening and spans the socket opening and through the central opening of which the water-releasing end of the water outlet can be introduced into the socket interior.

Ce raccord adaptateur se caractérise en ce que l'unité d'appui (14) est constituée d'un premier élément de renforcement (18) en forme de disque et d'un second élément de renforcement (22) en forme de disque possédant chacun une zone annulaire extérieure continue (19, 23) à partir de laquelle s'étendent plusieurs languettes (20, 24) réparties de manière régulière sur la circonférence, articulées à la zone annulaire (19, 23) au niveau de leur base (25, 27) et orientées radialement vers l'intérieur ainsi que de façon inclinée par rapport à l'axe longitudinal (3), en ce que les languettes (20) du premier élément de renforcement (18) en forme de disque définissent entre elles, à l'état non élargi de l'élément d'étanchéité (12), un espace libre (28) qui correspond, pour ce qui est de ses dimensions, au moins essentiellement aux dimensions des languettes (24) du second élément de renforcement (22) en forme de disque, en ce que les languettes (24) du second élément de renforcement (22) en forme de disque définissent entre elles, à l'état non élargi de l'élément d'étanchéité (12), un espace libre (29) qui correspond, pour ce qui est de ses dimensions, au moins essentiellement aux dimensions des languettes (20) du premier élément de renforcement (18) en forme de disque, en ce que les éléments de renforcement (18, 22) en forme de disque sont conçus de telle sorte qu'à l'état monté, les languettes (20) du premier élément de renforcement (18) en forme de disque viennent se placer dans l'espace libre (29) séparant les languettes (24) du second élément de renforcement (22) en forme de disque et remplissent ou couvrent au moins essentiellement ledit espace (29) et vice versa et en ce que les languettes (20, 24) forment ensemble l'entonnoir pouvant être élargi.
